Laser soldering is a process which selectively heats solder by means of laser irradiation (usually utilizing a direct diode laser) which forms a bond between two parts. Advantages of laser soldering include: Localized/selective heat input. Ideal for heat sensitive components.Laser soldering is a technique where a precisely focused laser beam provides controlled heating of the solder alloy leading to a fast and non-destructive of an electrical joint.: a pointed or wedge-shaped device that is usually electrically heated and that is used for soldering.Laser soldering is much faster and achieves efficiency unattainable for traditional methods. This is the only way to solder microscopic components and materials that are sensitive to high temperatures. Moreover, laser soldering is very clean and leaves no traces on the PCB.
